Although sintered wire with lower resistance was preferable as a scan line and a signal line in conventional art in order to make a voltage drop small, there was a problem in electric connection with an electrode which constructs a cathode. In the present invention, a cathode which has an electron-emitting region 16 on a substrate 10 is constructed of a base electrode 11 , a top electrode 13 , and a protective insulating film 14 sandwiched by these electrodes, the base electrode 11 becomes a signal line, and sintered wire 18 , used as a scan line, and the top electrode 13 are connected with an sub-electrode 17 . The sub-electrode 17 includes metal included in the sintered wire 18 , and metal included in the top electrode 13.
